BACKGROUND The approximately 350 demosponge species that have been described from Antarctica represent a faunistic component distinct from that of neighboring regions. Sponges provide structure to the Antarctic benthos and refuge to other invertebrates, and can be dominant in some communities. Despite the importance of sponges in the Antarctic subtidal(More)
Although decapod crustaceans are widespread in the oceans, only Natantia (shrimps) are common in the Antarctic. Because remoteness, depth and ice cover restrict sampling in the South Ocean, species distribution modelling is a useful tool for evaluating distributions. We used physical specimen and towed camera data to describe the diversity and distribution(More)
Submarine canyons are dramatic and widespread topographic features crossing continental and island margins in all oceans. Canyons can be sites of enhanced organic-matter flux and deposition through entrainment of coastal detrital export, dense shelf-water cascade, channelling of resuspended particulate material and focusing of sediment deposition. Despite(More)
The New Zealand International Polar Year–Census of Antarctic Marine Life (NZ IPY-CAML) project added to previous benthic studies in the Ross Sea by extending sampling north from the continental shelf to previously unsampled areas of the shelf break, slope, abyssal plain and seamounts in the region. The aim of the current study is to give first insights into(More)
Limidae) comprises species mainly occurring in the deep sea on hard substrates or canyon walls (Johnson et al. 2013), where hydrodynamic conditions enhance the supply of suspended food. During a survey of Scott and Admiralty seamounts as part of the New Zealand IPY-CAML expedition in 2008, a number of new records and new species were documented (e.g.,(More)
Although initially viewed as oases within a barren deep ocean, hydrothermal vents and methane seep chemosynthetic communities are now recognized to interact with surrounding ecosystems on the sea floor and in the water column, and to affect global geochemical cycles. The importance of understanding these interactions is growing as the potential rises for(More)
BACKGROUND Accident and Emergency (A and E) is the first port of call for most people who have experienced an injurious fall. This provides the potential for identifying patients who may benefit from preventative interventions. This study aims to estimate the percentage of falls attendances that are not recorded on computerised A and E records. METHODS A(More)
We report a remarkable case of ‘bipolarism’, where two different polar species, namely Lebbeus polaris in the northern hemisphere and Lebbeus kiae n. sp., here described from the Southern Ocean, have been found to share similar ecologies. Despite the great geographical distance between the two species, both show high host fidelity in associations with two(More)
1. Plasma levels of L-aspartate:2-oxoglutarate aminotransferase (AST) were estimated in Hereford cattle, 1 month to 12 years of age, kept under range conditions and in a group of Hereford x Angus cows kept on the same range. 2. Plasma levels of AST were estimated in a group of Crossbred cows and their calves fed a constant diet and kept in individual pens(More)
UNLABELLED We have asked, is hypertriglyceridemia in the fed state in pregnancy due to intolerance to exogenous fat, accumulation of endogenous triglycerides, or accumulation of remnants of d < 1.006 lipoprotein metabolism? To answer these questions, we fed fat-free diets high in starch or sucrose, or diets containing fat or fat plus cholesterol to pregnant(More)
